Deinonychus or Deinonychus antirrhopus is a genus of dromaeosaurid theropod dinosaur with one described species, Deinonychus antirrhopus. Deinonychus or Deinonychus antirrhopus which could grow up to 11 ft. long, lived during the early Cretaceous Period, about 115 to 108 million years ago.
Fossils have been recovered from the U.S. states of Montana, Utah, Wyoming, and Oklahoma, in rocks of the Cloverly Formation, Cedar Mountain Formation and Antlers Formation, though teeth that may belong to Deinonychus or Deinonychus antirrhopus have been found much farther east in Maryland.
“Terrible claw” refers to the unusually large, sickle-shaped talon on the second toe of each hind foot. The fossil YPM 5205 preserves a large, strongly curved ungual. As in other dromaeosaurids, the tail vertebrae have a series of ossified tendons and super elongated bone processes. These features seemed to make the tail into a stiff counterbalance, but a fossil of the very closely related Velociraptor mongoliensis had an articulated tail skeleton that is curved laterally in a long S-shape.
Based on the few fully mature specimens, Deinonychus or Deinonychus antirrhopus could reach 3.4 meters (11 feet) in length, with a skull length of 410 millimeters (16 in), a hip height of 0.87 meters (2.9 ft) and a weight of 73 kg (161 lb), though there is a higher estimate of 100 kg (220 lb).
The skull of Deinonychus or Deinonychus antirrhopus was equipped with powerful jaws lined with around seventy curved, blade like teeth. The skull of Deinonychus or Deinonychus antirrhopus was different from that of Velociraptor, however, in that it had a more robust skull roof, like that of Dromaeosaurus, and did not have the depressed nasals of Velociraptor. This suggests that, in life, the tail could bend to the sides with a high degree of flexibility.
